Leveling Roulette -- Full Group -- Penalty

[Iscah]

kind of defeats the purpose of it being a "roulette" if you're trying to game the system, no?

Joining the roulette as a full party kind of defeats the purpose of the roulette anyway, at least in part, because roulette queues are supposed to supply party members to people queuing for specific dungeons. Presumably that's why they've allowed for the limited dungeon choice in a full party because it doesn't affect anyone but the party themselves.
